-===== QtSoundModem Settings =====+===== WhatsPac =====
  
-**NOTE: The new NinoTNC 3600 bps mode does not yet work with QtSoundModem, but compatibility is being worked on! Unfortunately the 2400 bps mode mentioned below will no longer work with the node.**+WhatsPac is a great new application for packet that has chat channels and private messages. Visit http://whatspac.m0ahn.co.uk:88/ for more information. Note that the project is in alpha so a few things are still being ironed out.
  
-If using [[https://www.cantab.net/users/john.wiseman/Documents/QtSoundModem.html|QtSoundModem]] as a modem, you should select "QPSK V26A 2400bps" and a centre frequency of 1500 hz.+{{:nodes:whatspac.png?400|}}
  
-{{:nodes:qtsm-gb7bsk-2m.jpg|}}+It is possible to route to the main WhatsPac server node [[nodes:mb7npw|MB7NPW]] from GB7BSK, although the most stable route includes one AXIP link, the rest is all RF. Have a look a the **[[https://nodes.ukpacketradio.network/packet-network-map.html?rfonly=1|packet map]]** to get an idea of routes and feel free to drop 2E0HKD a message by packet mail or on the OARC discord if you need help with routing.

 To do this from a BPQ node, use the "nc" (new connect) command, rather than the more common "c" (or "connect") command, and force L2 (no NET/ROM) by putting an exclamation mark in front of the callsign.

 One advantage of this type of connection is the ability for SREJ, or selective reject, to be used. Normally, several packet may be sent out in order, and if one of them is not received correctly the entire batch is rejected with a REJ message. The whole set of packets then has to be retransmitted. SREJ allows only specific packets to be rejected, so only those individual packet need to be retransmitted. One advantage of this type of connection is the ability for SREJ, or selective reject, to be used.

 +As of BPQ version 6.0.24.69, netrom L4 connections will use AX.25 2.2 for the underlying L2 connection, with all the SREJ benefits without you having to do anything else.
